Burbot

The burbot , also known as bubbot, mariah, loche, cusk, freshwater cod, freshwater ling, freshwater cusk, the lawyer, coney-fish, lingcod, or eelpout, is a species of coldwater ray-finned fish native to the subarctic regions of the Northern hemisphere. It is the only member of the genus Lota, and is the only freshwater species of the order Gadiformes. The species is closely related to marine fish such as the common ling and cusk, all of which belong to the family Lotidae (rocklings). The name burbot comes from the Latin word barba, meaning beard, referring to its single chin whisker, or barbel. Its generic and specific names, Lota lota, comes from the old French lotte fish, which is also named "barbot" in Old French.
